Codeforces Round 871 Div.4: clear and detailed explanations
I enjoyed a lot resolving this contest, regardeless the stuck that I had on problem G (Hits different) and H(Don't blame me). Reading the tutorials or seeing other guys videos, it doesn't help me a lot. Beacause these guys don't explain clearly how come the solutions, certainly because they are smarter than me and the solutions seem abvious for them.
If this was happend to you, just bare with me and see my presentaions where I clearly explain the solutions of every problem in details. Enjoy :)
